To all whom t may concern.'

Be it known that l, ARTHUR il. Satire, vcitizen of the United States, and resident of the borough of Manhattan, city' of New .York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-NVriting Machines, of which the following is a specification. A i

My invention relates to typeisriting Inachines and more particularly to. the line lock, margin stop and. bell-ringer mechanism of such machines.

My invention has for its principal object to provide improved devices of the kind referred to. y

To the above and other ends, my inven tion consists in certain features of construe tion and combinations and arrangements' of parts, all of which will be fully set forth herein and particularly pointed out in the claims.

1n the accompanying drawings, Figure 1 is a partial front-to-rear vertical sectional view of a typewriting machine having my invention embodied therein. Fig. 2 is a rear elevation, partly in vertical section. Fig. 3 is au enlarged isometric View of the mar-` gin stop bar and the adjustable stop devices.

Fig. l is a partial top plan view of the line lock mechanism.

ln all 'or the views, parts areV shown in My inventionis applicable or adaptable to various styles ,of typewriting machines. rlhe main trame of the machine shown in the drawings, comprises two side pieces, each having a base part 1, front and rear corner posts 2, and a bar 3 connecting said posts at the top. Each of said side pieces also includes at its rear part an upward extension 4 and an inward and upward eX- tending bracket 5. Saidgside pieces are connected. together by variouscross bars and parts, including, in the base, a bar 6, and, :farther back, a broad bar 7; and at the top said side pieces are connected by a front top plate 8 and arear top plate 10, the latter sui-mounting the upward extensions The carriage, which has a roller platen 11 journaled therein, comprises end pieces or i :ackets 12, and front and rear grooved rails 1 3, the latter constituting parts ot ball bearings which also include balls llt ingkeys 1li on their forward ends.

and front and rear grooves in a stationary rail 15, which last is mounted on the bars 3 of the main frame. The end brackets 12 have a bar 16 secured thereto at 'their rear edges by means of screws 17. rI his bar is here shown made of angled sheet metal. The carriage can be propelled in its travel leftward by any suitable means, such as a spring drum 18 having a cord 19 running over a pulley 20 and thence to. a. fixture 21 secured to the carriage. rIhe feedV of the carriage can be controlled by any suitable escapement mechanism, comprising, in the present instance, an escapement rack bar 22 `mounted on the carriage by arms 23, and cooperating feed dogs 24:, here shown more or less conventionally, mounted on a dog rocker 25, pivoted in a bracket 26 secured 'tothe under side of the stationary rail 15. Said dog rocker is shown provided with an operating arm 27 and a restoring spring' 28. Said arm 27 is adapted to be operated by an arm 29 projecting iupward from a universal bar 30, pivoted at 31 in the base 1.

rl`he printing instrumentalities can, as far as my present invention is concerned, be of any suitable sort. n the present instance, they consist or types 32, on front strike type bars 33 which are pivoted at 3st in a type 4bar segment which segment is capable of a case shift movement to different positions. To this end, said segment constitutes part of a shift frame which also includes side bars 36, each eX- tending from the .segment 35 first toward the rear and thence upward, said bars being pivotedv at their extremities on pivot pins type bars eo, and other arms directed rearward and connected by vertical push links 42 with'the rear ends of key levers t3 hav- Said key levers are of the first order, being pivoted on wires 45, .supported on the under side of the cross bar 7, and they are prov vided with returning springs Mi. The construction is such that the depression of the rear ends of the levers 39, move horizontally in a front-and-back direction, said links swinging about their lower ends as pivots. It will be perceived that the sublevers are mounted in the shift frame and frame.

The type action and shift frame construev` tion shown herein and above described, are not claimed in this case, but are claimed in a prior application of mine filed April 25th, 1913, Serial No. 763,532.

My line lock mechanism includes a locking member, preferably a locking bail 47, adapted to'lock the sub-levcrs 39 and to do so, on occasion, in any one of the positions to which said subslevers are shifted. Said bail, as here shown, consists of a cross bar having two arms 48 and 4l) pivoted by means of pivot screws 5U to the inner sides of the side bars lo of theshift frame, the pivots 50 being above the rear ends of the sublevers 39 and nearer to the pivots 37 of the shift frame. lhe locking bail made of sheet metal, and the cross bar 47 has a stilfening flange 51 bent down from its rear edge. The arm 49 is prolonged 'upward beyond its pivot 5() and at its upper end it has an car or piu 52 bent out therefrom and engaging in a slot .in the lower end of a depending lug 53 bent down from one arm of a horizontal bell-crank 54, l? ig. 4, which bell-crank is pivoted on a pivot screw 55, threaded into the under side of the top plate 10. rl`he lever 54 has an arm extending forward 'from the pivot 5() and having at its end a downwardly bent lug 56 having its lower end bifui-cated to embrace a pin 57 i projecting from a margin stop and line lock bar 58. The construction is such that the top plate 10, which is secured to the parts 4 by screws, can be lifted Avertically oil of the machine, carrying the lever 54 with it, without disturbing the bail 47 or the bar 5S. Said bar 58 lies back o and parallel with the carriage, and it is mounted for endwise motion toward the lelt from its normal position, such motion acting to rock the lever 5l and, through said lever, lthe bail 47, causing said bail to move toward the front of the machine over the ends o'lE the sub-levers 39, indicated in. broken lines in'Fig. l. When non shift frame is shil'ted, the pivots 50 ol. the locking bail and said bail itself are shifted also, and said bail is capable of locking the printing mechanism in any one of the three positions of said shift frame. The bar 58 at its right-hand end is formed or provided with a round pin or stud 59 which takes a bearing in the right-hand extension 4 of the main frame. At its left-hand end said barhas a hole (SO extending longitudinally thereof, and into said hole there projects the reduced cylindrical end oi? a screw (51, which screw is threaded through the left-hand frame extension 4. A helical spring (32 in the hole (50, is compressed bctween the bottom olf said hole and the end of the pin (il, and holds the bar 58 normally in its right-hand position, in, which position Said bar holds the bail 47 in its rear or unlocking position. The bar 58 has enough freedom of movement toward the left, against the tension of the spring (l2, to lock the printing mechanism.

A bell-hammer (33 is mounted on the bar 58 by means ol.' a wire arm (34 which, as here shown, consists of an extension olf tin*- pin 57; or rather, said pin 57 is merely the upperA part of the wire (Si. lhe hammer (325 stands just forward oi' a bel] (35 which .is .si cured bya screw Gli to the base part l oi' the mainframe, the arrangement being.,r such that the bell can be rung by a rocking ol' the bar 58 about the pins 5U and (il. Such rock ing in one direction is caused by a spring (3T acting on the Wire 57, (il, the motion ol which under the impulse of said spring is limited by a stop pin (38 projecting from the framework into the path olf the wire at the upper part thereof. Said pin normally holds the ham'mcr (33 a little away from the bell, :Ls-shown, so that, when the hammer is raised and dropped as will be presently cx plained, it strikes the bell by the spiing'iin.r of the parts.

A margin stop piece and a lino loch and bell-ringer stop piece are adpistaiily mounted on the 'bar 5S, which bar has, lor this purpose, a series ot notches of? cut in its under sido or edge at letter space intervals. The line lock and bell ringer cstop piece 7o, as best shown in Fig. 3, consists ol a piece olt sheet metal punched out and bent up to suitable form.y and finished in certain rcspects that will be referred to. Said pirre oi' sheet metal so folded that the llat middle part of it comes behind tho har 58, whence the metal is folded forward above and below the bar. At its upper edge, said stop piece has an ear 7l il`o|dud down in iront ol' the bar 5in', and serving as a guide to re\fcnt baclnvard motion ol said stop piece, and two other ears 72 and 715, bent up l'roin theloweredge, perform a lil ofliii ,'l1ioii. The stop piece is thus folded around three sides oil' the bar a nd l'roin itsl ircc edges, guiding ears are 'Folded against the Fourth side. The ear 75 is at the left-hand end of 'lith lll;

` a suitable distance to the right of the line locking stop 73. This eer projects liorizontally iorwsrd, and 1t hns its iront edge 75 inclined forward and toward the left, as

shown, und its leftehnnd edge. 76 beveled upward toward the right. rl`he stop-piece is Wider up and doivn than the bnr 58, and a lint spring` 77, bowed downward in its middle, is under tension between the top of said bnr and the upper fold of said stop piece, said spring noting to press the lower fold of seid stop piece up against the teeth on the unde side of said bnr. Seid spring is bent sharply i'ipn'nrd at its ends so as to embrace the stop piece end to prevent said spring from escaping,I endn'ise. YThe bottoni fold o'l the piece TO has :in eer projecting from one end thereol and bent np ns shown, so ns to forni n tooth which lits into one of the notches (39 inthe bnr 5S, in which it nornndly held buv 'the spring; il'. The. oonstruction is such that by pressing down with the linger on the stop-piece :it its end where seid stop piece is ron'hened for the pin'pose, the tooth 78 is forced dovvn ont ot' engagement, after which the stop iliieee. een be moved by the. suine linger nloi Y the rod in either direction ton new udlnseninit, and upon release of the pressure. olI `the operators linger, the spring T7 will conse the tooth 'TS to engnge n notch G2.' and lock the stop-piece in its nen` posi ion. l'it will be perceived that the stopiliieoe consists of :i

` singrjlefpiece of sheet nieldl.

When the 82 passes the eur 724-, the ber 58 and herinner 63 drop beek and the bell is sounded. 0n the return ofthe carriage to the right, the eur 82 rides up on the incline 7G, rocking the lever 80 slightly, so that seid enr 82 con nieve back to the' right without disturbing the ber 58, or being itself arrest* ed by the lug or ear 74. A'terthe 'sounding of the hell, a. few more steps of the Carriage brings the enr or stop S3 into Contact with the abrupt edge of -the stop Tg5, moving the bar 5S toward the left and swinging the bail et? to locking position, and also arresting the carriage. ln order to provide 'for Writing additional letters after the operation of the line lock, the lever can be rocked to raise the enr S3 above the upper edge of the stop 73, ,nixerenpon the spring 62 will move the bur 58 to the right, and nlove the stop i3 in underneath the eur 83. The cnr-ringe con then step further to the left. When the ein' 82:3 passes the stop 73, it drops down to no1-nml position; but Vit does not prevent the 'carriage roin being freely drawn to the right, es the inclined lett-hond edge of the xnnrhine. the lordi-er from the appel* edge- :ind the leiter l'roin the lowes edn'e or 'the i lever. so that there cnrs lie with their l'lnt The upper enr e the le t, when the ein edge of frin ge.
